These systems
provide large-scale power generation from the sun and, because
of their proven performance, are gaining acceptance in the
energy marketplace. Parabolic trough is a type of solar thermal
collector and a high performance & high efficient Parabolic
Trough Concentrator Solar collector for use in Industrial
process heat application and utility scale Solar thermal power
plants. Parabolic-trough collectors can also drive absorption
cooling systems or other equipment that runs off a thermal load.

Principle

By tracking the sun
from sunrise to sunset, the parabolic Trough collectors
concentrate the sun’s radiation with their parabolic mirror
facets on the absorber tubes along their focal line. Through
these absorber tube circulates a heat transfer fluid (HTF) and
then deliver the thermal energy to a heat exchanger, where it
generates steam for power generation or industrial processes.
This fluid can be efficiently heated up to 4000C.
